i find a problem
when i need to use content.load<>(“path”) to load my texture, if the path is like ./a/a, i dont know what i should write to replace “path”
if i write
content.load("./a/a")(without blank)
, it will say"System.NullReferenceException:“Object reference not set to an instance of an object.”"
if i write
content.load("./ a/ a")(with blank)
, it will say"Microsoft.Xna.Framework.Content.ContentLoadException:“The content file was not found.”"
what right way to write path

Try specifying a decreasing slash \ instead of /.

ok, i found i make a mistake
i use
to try to add textures, this cause error, but i dont know what

List player;

player.Add(content.Load(".\player\player2"));//error ,path is ok if player is Texture2D[]

i see the programme, it say \ is replaced to /, maybe the problem is not path
i have solve the problem by rewrite there.

Send the project here

this is the problem code example, replace Texture[] to List<> and initial can solve bug

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using System.Collections.Generic;

namespace MyGame;

public class Game1 : Game
private GraphicsDeviceManager _graphics;
private SpriteBatch _spriteBatch;
//public List role = new List();
public Texture2D[] role;

public Game1()
    _graphics = new GraphicsDeviceManager(this);
    Content.RootDirectory = "Content";
    IsMouseVisible = true;

protected override void Initialize()
    // TODO: Add your initialization logic here


protected override async void LoadContent()
    _spriteBatch = new SpriteBatch(GraphicsDevice);

    role[0] = Content.Load<Texture2D>("player1");
    role[1] = Content.Load<Texture2D>("player2");

//error System.NullReferenceException:“Object reference not set to an instance of an object.”
role[2] = Content.Load(“player3”);
// TODO: use this.Content to load your game content here

protected override void Update(GameTime gameTime)
    if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))

    // TODO: Add your update logic here


protected override void Draw(GameTime gameTime)

    // TODO: Add your drawing code here



You have not initialised role.
you need to do:

List<Texture2D> role = new List<Texture2D>();

Then this should work:


(When you get the error, it is role that is not set to an instance of an object)
